The Willoughby's Return by Lois Lowry

"Many years before - thirty years to be exact - Mr and Mrs Willoughby had embarked on an extended vacation (they used the Reprehensible Travel agency), leaving their four children hehind. They didn't like the children very much (and to be honest, the children didn't like them, either), and so it was not a tragedy for them to be separated. But it would have been illegal for them to leave the children all alone (the eldest Tim, was just twelve). To keep things on the up and up, Mr Willoughby had advertised for a nanny."

It is now thirty years later. So much has happened. Tim is the boss of a successful candy company, he has a son called Ritchie. BUT the US congress have just banned candy following lobbying by the American Dental Association. The other three children are now adults, living in other parts of the US and all three have happy, but very different lives. Mr and Mrs Willoughby have been frozen in the Swiss alps all these years but now they have deforested. They are still the most unpleasant people you could ever meet and show no remorse for their treatment of their children. It is time for them to return but so much has changed.

This book is such a fun romp but I do think you will enjoy it even more if you can find and read the first instalment before rejoining the mayhem of the Willoughbys.

Blurb from the first book: The Willoughby children—Timothy, twins Barnaby A and Barnaby B, and their sister Jane—are fond all old-fashioned things, but especially old-fashioned adventures. What they aren't fond of, however, are their parents. Truth be told, their parents aren't the fondest of them, either, and they're concocting an evil plan to get rid of their children once and for all! Both parents and children have plenty of dastardly ideas and tricks up their sleeves. The only thing they don't have is any idea of what lies between them and a happily-ever-after.

Blurb from the second book: Although they grew up as wretched orphans, the Willoughby siblings also became heirs to the the Melanoff candy company fortune. Everything has turned out just splendidly, except for one problem: Richie Willoughby, son of Timothy Willoughby, is an only child and is quite lonely. Winifred and Winston Poore have long admired the toys of their neighbour Richie Willoughby and finally befriend the mysterious boy next door. But just as Richie finally begins to make friends, selling sweets is made illegal, and the family's fortune is put in jeopardy. To make matters worse, Richie's horrible Willoughby grandparents—frozen atop a Swiss mountain thirty years ago—have thawed, remain in perfect health, and are making their way home again. What is the point of being the reclusive son of a billionaire when your father is no longer a billionaire What is the future without candy in it And is there any escaping the odiousness of the Willoughbys.

The threads of the story, with various tales of parents gone missing, fortunes lost or never found, and good luck in the end, are gathered most satisfactorily and warmheartedly. Highly amusing. Kirkus

If you enjoy the two Willoughby books you are sure to also enjoy A Series of Unfortunately events and by chance I have just started reading Leeva at Last by Sara Pennypacker - a book that would be simply perfect to read before or after the two Willoughby books.

One special feature of The Willoughbys return are the fun footnotes which often reference contemporary culture especially because Mr and Mrs Willoughby have missed all the innovations of the last thirty years. Words like uber, google, Brexit, HBO, satellite radio, Twitter, FaceTime and Skype are so confusing.
